You mean a GMP Cobra like this? Just got this about a week ago. 30 years old and still in the original box. Came with an almost new OS46 FX R engine. On the box it says it has auto rotation and a inline swash plate. Chopper was never flown and the engine was only broken in. Has the original main blades,all the original manuals,unpainted canopy and the ball muffler. My first chopper. Switched over from jets so hope I can put it together right.
